This is Lacey Chabert's twenty-third Hallmark Channel movie. Her first one was Elevator Girl (2010).
The inn looks like The Mistletoe Inn in the Alicia Witt movie of the same name (The Mistletoe Inn (2017)). The doors of each guest room are identical in both movies.
This is the third movie executive produced by Blake Shelton and his mother Dorothy Shackleford, and based on his song "Time for Me to Come Home", the first movie, Time for Me to Come Home for Christmas (2018), and the second movie, Time for You to Come Home for Christmas (2019). While all three movies are produced by Front Street Pictures for the Hallmark Channel, each movie is independent of the other and has a different story line, actors, and setting.
The story is a romantic riff on Agatha Christie's classic murder mystery "Ten Little Indians," wherein a group of disparate strangers with one common bond is brought together by an unknown, unseen host.
This movie was inspired by Blake Shelton's song "Time for Me to Come Home" from his 2012 holiday album, Cheers, It's Christmas. Blake wrote the song with his mother, Dorothy Shackleford, who also sings on the song and who published a book (also inspired by their song) titled Time for Me to Come Home in 2013.
